She walked in one direction and he in the other. Dix stopped in his tracks. "I must paint you, I simply must! You represent an entire epoch." She was amused. "You want to paint my lacklustre eyes, my ornate ears, my long nose, my thin lips. You want to paint my short legs, my big feet - things that can only frighten people and delight no one?" To Dix, her depiction was perfect. The portrait would represent a generation concerned not with the outward beauty of a woman but her psychological condition.

...As you can see it’s pretty unforgiving. von Harden’s pose is an odd mixture of relaxed (elbow on the back of the chair, droopy stockings, half-open eyes) and neurotically tense (clawed left hand and fixed grin/snarl). The dominant reds add to the overall feeling of angst, making it quite an edgy painting given that it shows someone sitting in a cafe having a casual cigarette.
